Patented June 2, 1896.

UNITED STATES PATENT OFFICE.

AUGUST GROSS, OF NEW YORK, N. Y., ASSIGN OR TO THE MANHATTAN BRASS COMPANY,

OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 561,108, dated June 2, 1896.

Application filed October 30, 1895.

T0 @ZZ whom it may concern.-

Be it known that 1, AUGUST GROSS, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Improvement in Extinguishers for Lamp-B urners, of which the following is a specification.

My invention relates to an automatic gravity-operated extinguisherof simple and efficient construction and adapted to flat-wick lamp-burners.

In carrying out my invention I employ two similar extinguisher-blades having lips that meet centrally and longitudinally'over the wick. These extinguisher-blades occupy an inclined position and are provided with footpieces that take a bearing in a base-plate that surrounds the wick-tube above the perforated air-distributer. As the Wick is raised in the ordinary manner the extinguisherblades are parted and the edges of their lips come at opposite sides of the wick and their foot-pieces swing down and come in contact with the metal to form a stop. As the wick is drawn down the inclined extinguisherblades fall automatically and by gravity and their lips come together over the wick and put out the light.

In the drawings, Figure 1 is an elevation of a lamp-burn er, showing my improvements, the elevation being flatwise of the wick and wicktube. Fig. 2 is a similar elevation edgewise of the wick and wick-tube. Fig. 3 is a crosssection in larger size, showing the parts of the extinguisher, the wick-tube, wick, and airdistributer. Fig. 4 is a plan view of the parts shown in Fig. 3, and Fig. 5 is a plan View of the base-plate.

The burner shown is of a well-known flatwick form, and among the parts comprising the same are the base a, perforated air-distributer 1), spring chimney-holding arms 0, conical deflector d, wick-tube e, and vaportube 6'.

The extinguisher-blades f f are similar,- and each consists of a plate 2, lip 3, and footpiece 4, of approximately the form shown.

The base-plate h is provided with a central mortise 5 and opposite parallel mortises 6 7, and the central mortise 5 receives the Serial No. 567,426. (No model.)

wick-tube e and vapor=tube e when said baseplate is forced down over the same to place above the air-distributer h.

The foot-pieces 4 are narrower than the plate and lip portions, and they extend through the mortises 6 7 and between the plate h and the air-distributer, and the edges of the lip-pieces 3 are parallel and meet centrally over the wick and extend longitudinally to cover such wick.

In the position shown in Figs. 3 and 4 the wick is depressed and the lips of the extinguisher closed over its upper end, as would be the case in putting out the light.

The foot-pieces 4 where they pass through the mortises G 7 act the same as hinges, upon which the extinguisher-blades swing, and these blades incline toward the wick, and as their major parts are the blades 2 and lips 3 the preponderance of weight is within vertical lines drawn through the mortises 6 7. Hence the action of gravity is to keep the extinguisher-blades closed.

As the wick is elevated, as shown in Figs. 1 and 2, it parts the extinguisher-blades and their lips bear upon opposite sides of the wick, while their foot-pieces just touch the top of the air-distributer b. In this position, and before the wick is entirely depressed, the straight edges of the lips serve advantageously to clean off the top of the wick from incrustation.

I claim as my invention- The combination with a lamp-burner, of a base-plate having a central mortise to receive the wick-tube and two opposite and parallel mortises 6 7, two extinguisher-blades each comprising a foot-piece, plate and lip, the footpieces passing through the mortises 6 7 and coming between the base-plate and air-distributer of the burner, and the extinguisherblades being inclined and the lips adjacent to the wick, substantially as set forth.

Signed by me this 26th day of October, A. D. 1895.

AUGUST GROSS.
